top to the bottom of said casing, leaving lateral space 7 into which space the intake pipe 2 opens. Air entering space 7 through intake pipe 2 flows into mixing chamber t3 throiieh the perfora-ions of member 5 `whereby said air is broken up into fine currents and particles thus facilitating its mixture with atomized fuel thrown into said chamber and against the inner Wall thereof. The intake pipe 2 may be adapted to be connected by any suitable means to a suitable receptacle (not shown) which communicates with the outer atmosphere and has its interior heated by the exhaust pipe (not shown) or other suitable means, so that heated air will be drawn into the mixing chamber 6.

A butterfly compensating valve 8, which is located in the intake pipe 2 to control the passage of air into the mixing chamber 6, is secured to a rod 9 that extends transversely through said intake pipe and is revolubly supported in openings in a pair of oppositely-disposed lugs l0 borne thereby. A butterlly throttle valve ll is secured to rod l2 and is located in the outlet pipe 3 to control the passage ci the mixture of fuel and air from the chamber il into the manifold, said compensa ing valve and said thrcttleefalve being preferably operatively the parts associated therewith being preterably constructed, arranged, and' operated as more particularly described and shown in my said prior application tor patent.

' ollow member 17 is adapted to be secured below flange 16 by means of a pair of screw-bolts 22, each bolt being provided with an opening 2-l therethrough, said bolts being adapted to extend through appropriate openings therefor in the bottom of re,- ceptaele 15, and flange 1li. and being adapted to engage serew threads in the vertical bores V 2O in the end-pieees of hollow member 17, said sere.\'-bolts so applied being adapted, also, to secure the parts mentioned iirinly in place in position as best seen in VFig. l, and the openings 23 oi'said screw-bolts being adapted to establish eommunieation between the inside of receptacle l5 and the bores of said hollow member l?.

rllhe upper end of hollow member 13 'is provided with a bearing 2l having a bore of reduced size to that ot the remainder or" the hollow portion of said hollow member, in whieh bearing an atomizer consisting of a tube having a dome-shaped top with a relatively small eentral opening 26 rotatably mounted so that its dome-shaped top may extend into substantially the center ot the bottom of the mixing chamber (3, as best seen in Fig. 1. The lower end of said atoinizer is adapted to extend through and below the lower end of hollow member 155 and bears a knurled knob 27 which is seeured to said end by any suitable means` sueh, for instance, as by means of solder, serew-threads,

ont? like, said knob having a central Ser-@w1 thjfabded opening therethrough adapted to engage corresponding serew-tln-ezuls borne by the intermediate piece ot hollow member uf?, thus sul. portingr said atomizer adjustably -in position on said intermediate piece so that by means et turning said lniurled Meegos knob said atomizer may be adjusted in its bearing, and, by means of spring-actuated pin 2S supported in an appropriate opening therefor through one ot' the end-pieces of hollow member 17, said knob may be looked against movement in any set position of said atomizer, said pin lia-ving a point or end adapted releasably to engage the serrations of said knob, as best seen in Fig. 3.

A pluralityy of comparatively small openings 29 are provided in the side of the portion of atomizer 25 inelosed within the enlarged Chamber ot' hollow member 13 below bearing 2st, said openings being adapted to establish communication between said enlarged chamber and the interior of said atomizer so that air entering said enlarged chamber through the lower end of said hollow nienibher 13 may flow intov they interior of said atomizer. A bearing 30 is borne by the inner wall of atomizer and is rigidly secured thereto by. any suitable means, such for instance,- as by means of solder, in the upper portion of said atomizer above openings 29 thereof and below the dome-shaped top of said atomizer, said bearing being adapted rotatably to support a comparatively slender tube or 31 mounted therein, which tube is adapted to have one end extending vupwardly within said atomizer above said bearing 30 toward but not quite reaching opening 26 ot atomizer 25, the

openine ot' said end being in axial alinement with and slightly smaller than said opening 26, and theA other end of said tube being adapted to entend downwardly below said bearing within said atomizer and being rig# idly secured, in any suitable manner, in vertioal bore 2l in the intermediate piece of hollowniember 17, so that said tube is adapted to eoinmunieate with said b ore and thence with the inside of reeeptaole 15 through bores 1H, 20, and 23. Bearing 8O is provided with a plurality ot' openings or perfor-ations said periorations being adapted to establish eonlmunieation between the upper and lower portions of the interior of said atomizer so that air entering said atomizer through openings 25) therein may, also, flow upwardly through perforations 32 in bearing 30 into the upper portion of said atomizer and on through opening 2G into mixing chamber (l.

By manipulating knurled knob 27, atomizer 25 may be raised or lowered with refer- .and fuels, and for all changes in temperature f and altitude.

License The construction and operation of the carbureter shown and described is such that a proper mixture of air and gasolene to provide a. practically perfect fuel for all changes in temperature and altitude Will result when said earbureter is used; the expansive power of air being greater at a low temperature than at a high-temperature, an adjustable atomizer is4 provided which may be regulated to admit a proper atomized fuel through said atomizer into the mixing chamber suitable to atmospheric conditions whether of temperature or rarelied condition. Moreover, the atomizer is adapted to be automatically lockedin any adjusted position by means of spring-actuated pin 28 pressing its point against the serrated' edge of knurled knob 27. j

A float 33., which surrounds a depending member 34 that is borne by casing l within receptacle 15, is slidably mounted on said member and is provided with mechanism 35 for controlling the flow of fuel into receptacle 15 from fuel supply pipe 36 through valve-chamber 37, said float, the mechanism for controlling the iow of fuel, and the parts associated therewith being as shown in the accompanying drawings and as more partic- .iilaily shown and described .in my said prior application'for patent filed November 28,

iaia'seriai No. '803,479 (Patent 1,145,898,

rviug. 3, 1915). Valve-chamber 37 is preferably formed by providing a partition wall i 3S vertically between the top and bottom of l *im inside of casing 1, as best seen inLFigs.

ad af 'the accompanying drawings, and

lvalve-stem 39 and all other parts associa-ted with said valve-stem and said valve-chamber are preferably constructed and arranged as shown in the drawings and as more particularly shown and described in my said prior application for patent.

ln operation, atomizer 25 having been ad justed Liii the manner hereinabove described,

sand fuel having been admitted into receptacle 15 from whence it will How into tube 31 through bores 23 of screws 22 and through the bores of hollow member 17 until it rises in said tube to substantially the level of the fuel in said receptacle, and throttle-valve 11 and compensating-valve 8 having been properly adjusted, the suction stroke of each piston of the engine will cause a vacuum in mixing chamber 6 and space 7, whereupon atomized fuel will be drawn into said mixing chamber through opening 26 in the dome of said atomizer. vAiir admitted into the interior of casing 1 through intake 2 will strike perforated wall 5 of mixing chamber 6 and will enter said'mixing chamber in line streams or y divisions through the perforations of said wall, thus facilitating the proper mixing of atomizedfuel and 'air in said mixing chamber.
